Sandra, an expert computer user, hears five beeps while booting her computer, which has AMI BIOS;
and after that, her computer stops responding. Sandra knows that during the booting process, POST
produces different beep codes for different types of errors. Which of the following errors refers to
this POST beep code?
A.
Processor failure
B.
Display memory error
C.
Motherboard timer not operational
D.
Cache memory test failed
Explanation:
POST AMI BIOS produces five beep codes whenever there is a problem of processor failure. The
different beep codes of POST AMI BIOS are as follows:
1 beep – Memory refresh timer error
2 beeps – Parity error in base memory (first 64 KB block)
3 beeps – Base memory read/write test error
4 beeps – Motherboard timer not operational
5 beeps – Processor failure
6 beeps – 8042 Gate A20 test error (cannot switch to protected mode)
7 beeps – General exception error (processor exception interrupt error)
8 beeps – Display memory error (system video adapter)
9 beeps – AMI BIOS ROM checksum error
10 beeps – CMOS shutdown register read/write error
11 beeps – Cache memory test failedC, B, and D are incorrect. All these errors have different POST AMI BIOS beep codes.
